Mono-Block Ceramic Pressure Sensors
Technical Data
The listed specifications and dimensions are subject to change without prior notice.
Notes:
1. For customized pressure ranges, consult BCM.
2. “fs” means full scale and refers the maximum working pressure or rated pressure.
3. Measured at full scale pressure.
4. Combined non-linearity, hysteresis, and repeatability.
5. Calculated as a rate of output change between 25°C and 70°C, and normalized by the output at 25°C, when the sensor
is not temperature compensated.
6. Response time for a 0 bar to fs step change, 10% to 90% rise time of leading edge.
